The affecting story of a scientist seesawing inescapably through time, this brilliant work effectively deconstructs most time-travel stories that came before. Winner of the 1989 Nebula Award for best short story. A man inventing a time machine using Dirac's theories of negative energy travels to the 1960s and discovers he can participate in the past, but not change it (Nebula Award 1989).

Both a documentary and a comedy. It features a man on a canoe tour of the Great Lakes while the geological time frame changes around him. He finds himself atop the great glacier, and then suddenly falling from the sky as it is removed. His canoe teeters from a cliff after the shoreline vanishes. He sips pure water from the lake as it suddenly changes to a modern polluted state. A lesson in geography, which concludes that although the Great Lakes have had their ups and downs, nothing has been harder to take than what humans have done to them lately. In the film, a lone canoeist lives through the changes of geological history, through Ice Age and flood, only to find himself in the end trapped in a sea of scum.

Hale, an American astronaut dies and is reincarnated with other persons who have lived throughout all of human history and end up on a mysterious planet called 'Riverworld'. The humans are left to their own devices and create tribal fiefdoms and succumb to brutal wars and raids. A mysterious race of hooded 'beings' oversee them - sometimes intervening, but their motives are unknown. Anyone who has ever lived and died on Earth comes here rather than 'the afterlife', even an extra-terrestrial call Monat, who had the unfortunate luck of dying on Planet earth in 2039. Hale leads a revolt and joins with others on a large boat to explore this mysterious new world. After an astronaut crashes, he finds himself in a rejuvenated body on a Waterworld. He also finds that he is surrounded with souls from many different eras and an alien being that died on Earth in the future. Immediately captured by a ruling group, the astronaut finds himself leading a group fighting for freedom. Also the soul of Nero Claudius has found its way to Riverworld and wants to resume his role as Emperor.

Road Rovers is an animated action/adventure series starring the most buffed-up and powerful howling hounds ever to walk the planet. The series features fur-raising adventures of man's best friends (actually, the pets of various Heads of State from around the globe)--courageous canines who doggedly defend and protect all that's good in the galaxy. In the town of Socorro, New Mexico (one year prior to the formation of the Road Rovers), Professor Shepherd is attacked by a man named General Parvo, who demands the professor's experimental transdogmafier (a play on the term transmogrifier) technology in exchange for his lost dog. Shepherd gives in but is tricked by Parvo, who gives him a bomb that destroys his laboratory. The next year, as normal dogs begin to mutate into monsters, Shephard, who miraculously survived the attack, realizes it is Parvo who is behind it and decides to stop him. Shepherd selects five dogs from around the world to combat this new threat. Once they arrive at his new, secret underground lab, he uses his new transdogmifier on the five, turning them into "Cano-sapiens" look like normal clothed humans except that they have retained all the trademark aspects of the dogs they came from, such as a tail, fur, distinctive ears and head, etc. Their personality before the transformation also remains intact. They can also speak English and possess super abilities that normal humans do not. When not fighting crime, they revert to their original dog form, and reside in the homes of the leaders of their country of origin; Hunter goes to the President of the United States, Colleen to the Prime Minister of the United Kingdom, Blitz to the Chancellor of Germany, Exile to the President of Russia, and Shag to the President of the Swiss Confederation. It is later discovered that many of the events in the past were caused by Parvo's time machine. These include Parvo's appearance in the past (as a cat named Boots), Parvo's failed attempt at constructing a transdogrifier causing Scout to become Muzzle, Boots becoming Parvo with Groomer's help, Muzzle meeting Hunter, and Shag saving Shepherd's life by informing him of the bomb that will blow up his lab.

Gertie lives on a mattress with all her stuff attached to her by wires so that it won't go wandering away in the no man's mist where time is in constant flux. I admit, though, that I didn't understand what was happening in the story which is mostly a conversation between Gertie and a younger girl in the misty land.
